Immediate pass was not necessary . VIP pass was probably the best value. Short wait time so your not standing in the cold too long. Regular line ....youll probably wait at least an hour for a 20-30 minute experience. I recommend walking a little bit slower and really taking in as many sites as you can. The compound has some very interesting items.
Give yourself 30 minutes once you get to the front gate to go through the haunted house and enjoy the monster museum at the end
